Hi,

I updated the HP Prime calculator with 20150617 , but have the same issues. I went to the provided ftp and did not found the the ultimate 10077 version, only the 20150617

I tried everything from re-installing the HP connectivity, firmware, entered in the 655 Diagnostis, etc. But the touchscreen does not work.

I'm an electrical engineer, and I followed the instructions. Also, I tried to use older firmware, but have the same issue.

I would appreciate any help to solve the issue.

Regards,

Hi!, @Ing_Ruben:

Can you with one point, of paper clip, into the Reset orifice in the back cover ?.

The battery, is fully charged ?. If not verify, in the HP PRIME, remove and check, with tester, in the indicated terminals.

[Ing_Ruben]

Yes is fully charged.

I did reset the calculator with a paper clip.

The issues continue

The image you sent did not came up!  You want me to remove battery and measure with a multimeter the battery voltage?

What would happen with the warranty if a remove the cover?
